This permits the third member to move freely over the top of the first member il so that the second member I2 can be positioned immediately over the rst strap member I i to place the sash in closed position.

Another feature of the present invention is that the hinge mounting described permits of adjustment of the tension placed upon each sash and the degree of frictional control maintained on the window so that its opening and closing the ends of the raised portion 22 inthe lrst strap.v4

member and by providing a simple, tapered,on

ventional screw 32 in this hole to extend into engagement with the adjacent frame. When the screw is driven into the frame with an ordinary screw-driver, the raised portion 22 bows and is drawn toward the sash frame. It is obvious that the simple screw 32v could be replaced by any other suitable member so long as it is adapted, when passed through said hole 3| and engaged with said sash frame 20, to draw the raised portion 22 toward the sash frame and hold it in any desired tensioned or bowed position. By reducing the space between the raised portion 22 on the rst strap member and the sash frame 20, one is able to tension the other portions of the hinge mounting and so provide a desired degree of irictional control between the shoes I4 and the raised portions 22. To this end, shoe I4 is so fashioned that it will pass the element 32. To eiect this, the shoe is preferably made in the shape of a U, as appears in Figure 8. However, a portion 33 of the U member is fashioned to t the first strap member snugly, ends 34 being crimped over to engage portion 22 snugly with a sliding it while the other portion 36 of the U member is spaced above the portion 22, as will be apparent upon comparing Figures 8 and 9. The range .of adjustment of strip ll is that permitted by the spacing between the bottom surfaces of crimped ends 34 of shoe I4 which rides along raised portion 22, and the adjacent supporting surface of sash frame 20.

Each second strap I2 on the following sash includes an arm I ilxed thereto between the hinge pin 23 and hinge 28 and extending therefrom, being each joined by a pin 53 in a hinge engagement with a travel bar 52 extending vertically in the sash frame I 64; each travel bar 52 is adjustable as to length to accommodate the spacing of the several upper sash. A clamp or guide 6B holds the lower free end of the bar in a spaced position in the frame although the end of the bar can flex, as will appear. A like arm 5 I a, provided on the lower sash, has a pin 54 thereon cooperatively adjacent a slot generally indicated at 55, arm 5 I a being slightly longer than vthe other arms and slot 55 being provided on the inside edge of each travel bar. The slot includes a semi-cir-v cular terminus 55A and 56 at opposite ends and an arcuate indentation 51 in the inside face 58.

A' cam member 59 is hinged on each travel bar' by a pin S I. The cam member includes an arouate tooth 62 projecting therefrom and normally overlying the arcuate indentation 51, as is shown' in Figure 4, and having an upper cam surface 68v and a lower cam surface 69 on each side of the tooth. The lower end 63 of the cam member 59 is enlarged so that the member is biased-bywgrav` indentation 51.

4 ity toward that position in which it is shown in Figure 4.

To lock the travel bar in any selected position by means of the lower sash, the end of the travel bar is provided with several spaced lateral projections 6B. A locking arm 61 is fixed on the strap I2 on the lowest sash to t within the projections, as is shown in Figure 5. With the lowest sash closed and locked (locking of the lowest sash is etfected by any suitable and conventional means), the sash will be in that position in which they appear in Figure 5 and the locking means will be generally as is shown in Figures 6 and 7. A sudden gust of wind, for example, may impart a closing force to the upper sash, thereby moving the travel bar until one of the projections 66 engages the stationary arm 61 and so holds the travel bar and sash against further movement.

'To manipulate the sash from the closed position in which these are shown in Figure Z, it is only necessary to unlock the usual sash fastening means utilized upon the lowermost sash (this lock is not shown in the drawing, being a conventional part of the sash). The lower sash is then moved outwardly; the initial movement of the lower sash brings the pin 54 on the arm 5Ia into engagement with the lower semi-circular terminus 56. Further outward movement of the lower sash moves the travel bar and the upper sash. The sash can remain in the open position of Figure l, the frictional engagement of the various shoes with the supporting strap members being suicient to retainthe sash in this position. If it is desired to close the lower sash, this can be achieved independently of the upper sash, a condition frequently desired, particularly since the sash are adapted to use in school rooms, auditoriums and the like. In this instance, the lower sash ls merely returned from its open v... position to a closed position, pin 54 moving upwardly along the depending and free end of the travel bar, as will be explained, into the position in which it is shown in Figure 5. In this position, the lower sash is eective to lock the travelbar against further movement, the lock'- ing arm 61 on the lower sash extending between two of the spaced lateral projections 66. as appears in Figures 5, 6 and 7.

As the lower sash is moved inwardly, the pin 54 rides up the inside face 58 on the slot 55 until it fits within the indentation 51 and is in engagement with the lower cam surface 69 on the cam member 59. Continued upward movement of pin 54 results in the positive engagement of the pin 54 with such lower cam surface whereby the cam member 59 is caused to rock about pin 6I into that position in which it is shown in Figure 3. In this position, the pin 54 is moved up to engage the side of the travel bar, as appears in Figure 6, the cam member 59 rocking back underfthe pull of gravity about pin 6I into that position in which it appears in Figures 5 and 6.

Upon opening of the lower sash subsequently, the pin 54 merely moves downwardly into engagement with the slot 55 immediately below the terminus 55A and the lower sash is again connected with the travel b-ar for positive movement of the latter. If one moves the lower sash too far outwardly, then the pin will slip into the This serves as a warning. The closing movement of the lower sash then closes all the sash.

From the foregoing, `I believe it will be apparent that.I have provided a relatively novel f and simpleform of sash.
